    A technique for strengthening weak passwords in electronic medical record systems
    (Springer Berlin Heidelberg, 2012) Maiga, Gilbert; Kalyango, Samuel Tusubira
    The internet has accelerated access to and sharing of electronic medical records (EMR). EMRs are meant to be confidential and only accessed or shared with authorization from the owner. A combination of UserID and a Password is the most widely used mechanism to assure user authentication and access to EMRs. However, these mechanisms have been greatly compromised by guessing and hacking of weak passwords leading to increased cases of medical identity theft, cyber terrorism and information systems attacks. This has resulted in false financial claims, debts due to unauthorized disclosure of the private and confidential EMRs leading to huge losses for the victims. This study developed a technique to strengthen weak passwords that integrates UserIDs, weaker password, salts, challenge responses and random variables to derive a stronger password for authentication. A system prototype to test the technique was built, tested and validated by users.
